Cleveland Golf Cobalt Jobber Drill 11.5mm

This cobalt steel jobber drill meets National Aerospace Standards 907 Type J for heavy-duty use. The 135-degree split point reduces walking and starts cleanly in stainless steel, tool steel, alloy steel and titanium. It is a single-piece tool designed for precision drilling in tough materials.

Check shank diameter and flute length before

The shank diameter measures 11.50 mm with a flute length of 94 mm and an overall length of 142 mm. Verify that your drill chuck accommodates the 11.50 mm shank and that the flute length suits the required hole depth. The tool carries a California Proposition 65 warning for a chemical known to cause cancer.

Straw finish and split point improve chip flow

The straw-coloured surface finish helps identify the cobalt grade and assists with chip evacuation during deep cuts. The 135-degree split point geometry is factory-ground to centre without a pilot hole, reducing thrust and heat buildup in hard alloys. No additional coatings or accessories are included with this single drill.
